The exclusive Cam System provides six (included 4 + Optional 2) interchangeable colour coded cams allowing you to quickly change the power and feel of the pedal to suit your individual playing needs. Changing from cam to cam is as simple as pushing the release button and snapping another cam in place. The Blue Cam provides a progressive action. The Blue Cam offers the very popular "off-center" axis type cam design. It offers a light feel in the beginning that accelerates with speed and power upon impact.
